Design of WSN with Relay Nodes Connected Directly with a LEO Nanosatellite

Abstract—There have been a few studies in the literature about using a Low Earth Orbit (LEO) satellite as a component of wireless sensor network (WSN). The satellite, as small as a Nanosatellite with a lifetime of three months, requires employment of a very simple payload whereas all the complexity is brought back to the relay nodes (RNs) which are connected directly to the Nanosatellite using a random access protocol. The mainly constraint on the design of this type of RN is its energy consumption which determine the lifetime of the WSN network. In this article, in order to calculate the energy comsumption of each RN, we will establish a mathematical model which takes into account all parameters involved for determining the lifetime of a RN for direct Communication with a LEO Nanosatellite. This model is completted by using discret event simulator. The simulations show that we could reach the maximum number of RNs that can be served by the Nanosatellite by implementing an optimized method of energy-saving on these RNs.
